HAN D-VISE.

SPECIFICATION forming part of Letters Patent No. 468,000, dated February2, 1892.

Application filed May 21,1891. Serial No. 393,662. (No model.)

To all whom it puny concern.-

Be it known that I, FRANK J. TOMEK, a citizen of the United States, anda resident of the city of St. Louis, in the State of Missouri, haveinvented a new and useful Improvement in Hand-Vises, of which thefollowing is a specification.

The objects of my invention are to have a hand-vise which can easily bereleased from the article which it is holding by the same hand whichholds the body of the vise, thus leaving the other hand free to graspthe article held by the vise, and also to enable the operator to releasethe article quickly, and thus save time which is consumed in releasingVises of the old pattern.

My invention consists in the arrangement and combination of parts hereindescribed and claimed.

I attain the objects of my invention by the mechanism illustrated by theaccompanying drawings, in which- Figure 1 is an elevation of my visewith the jaws of the vise open. Fig. 2 is a vertical section of thesame, showing the position of the parts when the jaws are closed. Fig.is a detached view of the release-lever D.

Ais an ordinary hand-vise having a handle and spring-jaws of theordinary form.

B is a bolt provided with a thumb-nut O with which to screw the jaws ofthe vise to gether.

P is a peg or projection extending from the body of the bolt B, and bycoming in contact with the inner surface of the lower jaw of thehand-lever prevents the bolt B from coming out of the vise.

E is another pin or projection projecting from the body of the bolt Band serves to hold the bolt B in place when the thumb-nut l is screweddown by impinging on the surface of the release-lever D and to releasethe lower jaw of the hand-vise A when it drops into the recess F. Therecess 13 is preferably formed by an inclined plane on the outer rim ofthe head of the release-lever D. The head of this lever D has a holethrough it, as seen in Fig. 3, for the reception of the bolt B, and isflanged, so as to receive the head of the bolt 13. The head end of thebolt B is provided with a feather b, which is adapted to move in and outin a groove in the jaw of the vise, which prevents the bolt B fromturning by the movement of the thumb-nut O. This turning of the bolt,however, may be overcome by making the head end of the nut square whereit enters the jaw of the vise.

It is obvious that when the pin E is placed at the point E on therelease-leverD and the article to be held is placed between the jaws ofthe hand-vise and the thu mb-nut O screwed down, and the operator wishesto hold the article held by the handlever with his nippers and releaseit from the hand-vise, all he has to do is to press the release-leveraround with his thumb or finger of the hand with which he holds thehand-vise until the pin E falls into the recess F when it is releasedand the other hand secures it. This is of great advantage towatch-makers and other persons working with small articles, as they canhold them with nippers in one hand and release them with the other, andthus avoid losing them.

Now what I claim, and for which I ask Letters Patent of the UnitedStates to be granted me, is

1. Ahand-vise consisting of a pair of springjaws, a bolt and nut bindingthem together, and a release-lever arranged along the jaw of thehand-vise and having an offset or recess, into whichaprojection on thebolt is adapted to drop when the release-lever is pressed to one side,whereby the jaws of the hand-vise are released by the same hand whichholds the hand-vise, for the purposes specified.

2. In a hand-vise, a movable lever provided with an oitset or recess,said recess being adapted to receive a pin or projection on the boltbinding the jaws of the hand-vise, a bolt passing through the jaws ofthe hand-vise and provided with a projection at the head end of thebolt, adapted to engage the surface of the movable lever and drop intothe recess when said lever is turned to one side, and the jaws of ahand-vise, all combined, substantially as described, and operating topermit the article held by the vise to be released by the same handwhich holds the vise.
